N-Switch Coverage refers to the measurement of sequences involving N+1 transitions within a system’s state space during testing. It evaluates how effectively test cases exercise different state transitions, ensuring comprehensive testing of the system’s behaviour.
Key Aspects:
- Assessment of Transition Paths: It examines sequences of state transitions to ensure all critical paths are tested.
- Thorough State Exploration: It ensures that a broad range of possible state transitions are covered during testing.
- Detection of Untested Paths: It identifies untested transition sequences that may hide defects or vulnerabilities.
Achieving high N-Switch Coverage enhances test quality by validating key state transitions and reducing the risk of defects in production. This approach ensures critical system behaviours are thoroughly exercised, improving reliability and robustness.
